To all whom it may concern: I

Be it kn'ownthat I H MILTON D. GUFFEY, a citizen of the United States, residing at Unionvillc, in the county of Putnam and State of Missouri, have invented certain new and useful Improvements in a Combination Road Grader, Drag, and Harrow; and I do declare the following, to he e full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

T 11s invention relates to improvements in a combined road grader, drag and harrow.

The object of the invention is to provide a device of-this character which may be readily arranged for use as a road grader and drag, or as a harrow, means being provided whereby the parts may be quickly adjusted for light or heavy Work. A further object is to provide a'road grader having means whereby the scraping blades vidc 0118 OI IHOIB transverse may be adjusted to throw the dirt to the right or left, as desired. I

With these objects in view, the invention consists of certain novel features of construction, combination and arran ement of parts as will be-more fully described. and 'particw larly pointed out in the appended claims.

In the accompanying drawings, Figure l is a plan view of'niy road grader, drag and harrow, with the parts arranged for use as a grader; Fig. 2 is an end View of the same; Fig.3 is a plan view showing the manner in which the device is adjusted to throw the dirt to one side or, the other; Fig. 4 is a longitudinal vertical sectional View showing the device arranged-as a combii ned'grader and drag, and showing the seat and draft adjusted for light work; andv 5 is a similar view of the device arranged :js a harrow.

In the embodiment of my invention, I pro ly disposed supporting bars 1, which are hingedly connected together at each end, and in the center hy longitudinally disposed links, 2; To the forward side of each the'bars 1 is adapted to be attached reversible scraper blades, 3, said blades being detectably secured to the bars by screws, bolts, or other suitable fastening devices. The blades 3 are preferably curved longitudinally, and are so disposed on-the forward sides of the bars 2 that the lower edge of the blade will project slightly below the lower edge of the bars, as shown. When one of the edges becomes worn the blades may be taken oil and reversed to bring the opposite edge into an operative position, thus providingfor the use of both edges of the I lades. g Adapted to be connected with the front or rear pivot bolt of the central link 2,. is a seat" supporting standard 4, in the up er rearwardly' projecting end of which is ormed a slot, whereby the seat 5 may be adjustablysecured thereto. The lower end of the standard 4 may also be bolted or otherwise secured in a bolt hole formed in the center link, 2, midway between the bars 1. By connecting the lower end of the seat standard 4 to the front or rear end or center of the link 2, the weight of the rider will be shifted,

thereby adapting the device for lightor heavy work.

To the upper side of the vehicle supporting bar 1, adjacent to its; opposite end, are secured upwardly rojectmg draft lugs 6, in which are forrne a series of vertically disposed openings 7, to one or the otherof which" is adapted -to ,be connected a suitable draft mechanism. By providing the plurality of openings, 7, the draft mechanism may bead-3 ustably connected thereto, thereby chang ing the position of the blade supporting bars.

to cause-the machine to do heavy or light r work, as desired.

' The draft device is here shown and referably comprises a transversely dispose draft bar, 9, which is. secured by chains or other flexible connections, 10, to the draft lugs, 6. ,Adapted to be slidably enga ed with the bar 9 is a clevis or attaching c ip, 12, between thev rear ends of which is mounted a bearing roller, 13, which is adapted to en 'age the om one rear side of the bar 9, and to roll end to the other thereof, thereby changing the draft from one side to the other of the machine. To the outer end of the clip12iis connected a Wlliflletrec -1'4,"to the opposite ends ofwhich are connected swingletrees, 15,v

to which the draft animals are adapted to be hitched.

By providing an adjustable draft device, such as herein shown and described, the machine may be quickly adjusted to throw dirt either to the right or left hand side of the road by simply placing the foot upon one of the rear corners of the device, which will cause the draft roller and clip to travel to the opposite end of the draft bar,'9, in which position the draft will be applied to the supporting bars to maintain thesame in an oblique position, while being drawn over the road, thus causing the dirt op osite side ofthe road.

combined scraper and drag, the rear scraping pulverize the same.

to be thrown to one side or the other of the machine. 'When it is desired to change the position of the supporting bars and scrapers, it is sim ly necessary to placethe foot on and hold own the opposite rear corner of the device, which will. cause the same to turn in the o posits direction, thus providing for the t irowing or scraping of the dirt toward the ed to the center pivot bolt of the forward bar,

thus rovidin fora single form of the device. A Wl ien the cevice is to be constructed for use as abarrow, the supporting bars 1 and the connecting links 2 are provided with teeth or spikes; l6, Which are a'da ted to project a sultable distance below t .e same, as

shown.

A road grader and drag constructed as herein shown and described, will be simple,

strong ,durablc and inexpensive in constructlon, and'by proy idmg a draft mechamsm for the same such as herein shown, the parts may be quickly changed without the use of yconncctions are :uljustahl secured to the levers or other operating devices to throw the dirt to one side or the other of the road.
